LACING-TIPPNG- MACHINE.

Application filed June 26,

This invention relates to an improved apparatus for forming tips on lacings suoli as shoe lacings, corset lacings,` and the like; and the object of this invention is to provide in such a machine or apparatus, means for feed ing the lacing into position to form the tips thereon and to remove the :lacing from the tipping means after having been tipped.

A still further object of the invention is to provide means including a plurality of setsof tipping devices and to provide means whereby' the .lacing is presented successively to these different tipping `devices to have tips formed thereon at intervals along itsl length.

Myinvention further consists in the provision of means for applying cement to portions -of the lacing vat .intervals along its ylength and to deposit stiifening core members into the treated portion of the lacing about the core to form tips at intervals along the length of the lacing.

A still further object of the invention is to provide means for drying the cement on the lacing tip while being formed.

Myinvention yfurther consists in the provision of means for severing each length of the lacing and removing the lacing from the tip-forming means after the cement has become set.

With these and other objects in view, the inventionconsists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

for opening the different valves along the cement receptacle for depositing cement on a plurality of' lacing strands as they are being drawn into the machine to have tips formed thereon at intervals along their lengths. i

Figure 7 is a top view of one of the .die blocks partly broken away to show the serl of cooperating tip forming dies therein.

Figure 8 is a sectional side elevation of the die bloclr with the tip-forming dies therein.

It is found in practice of advantageto be able tofeed a lacing fabric continuously to the dies to form tips at intervals along its length, and to provide means whereby the tip after having been formed on the lacing may be released and the lacing with its 1inished tip removed, all automatically.

It is also found of advantage to provide means whereby a number of the lacings may be operated upon simultaneously to form tips on each and so materially increase the production ofthe machine; andthe following is a detailed description of the present vembodiment of my invention in which one means is shown by which these advantageous results may be accomplished In order to provide means for automatically feeding the lacings` to thev dies, to be tipped and after having been formed to remove the lacing from the dies, I have provided a drum 10 which is mounted upon a of the drinn as desired.

Any suitable means for forming tips on the lacings, may be employed and mounted about the circumference of the drum, but I preferably employ aI set of tip-forming dies 26 mounted in the die block 27, one'pair of the dies 26 being mounted upon a slide plate 28 and operated by a lever'29, all as described in detail in my (1o-pending application Serial No. 719,299, Patent No. 1,592,422, granted July 13, 1926. n

The die operating lever 29 is provided with a roll 30 which as the drum revolves in the direction of t e arrow, is caused to engape u cani ill lixed upon a cross bur 532, sce Fininfo l, betiveen the trames 3?. whereby the dies at a predetcrn'linetl time ot the revolution ot the drum are caused to close upon the lacinp's` -lslto torni a tip thereon.

ln operating* upon the lacings 'll, each of which is led in trom its respective reel 35, each of ivhih is mounted on the shaft Btl, these lacings are passed through a short section ot tubing see Figure 5, which bends or shapes the lacingl into substantially cree` cent shape in cross section and into this short sect-ion oit tubingl l extend the discharge end oilE a nonzle 38 which leads trom the cement tant: 3D through the alve l0, and on each ot these valve; l provide :1 stem `atl on which is mounted a lever and all ot these levers are connected up by a bar t3, one end ot Which is truned downwardly as at 4d and is provided uit-h a roll which is arranged to Contact with the Cain lo on the side laee of the drum 10, whereby as the drum rotates the cam ttl is presented to the roll it and so opens all ot the valves l0, simultaneously, to deposit a given amount ot cement from the tank onto sections ot' the dillerent lacings as 'ted through their respective tubes, the valves being closed by action ot spring 823 When the cani has released the bar. The cement in tank 39 is under pressure which may be formed by any suitable means sueh as air pressure through a pump 4S, or by any other suitable means.

The valves are opened lor a suliieient length of time to permit the cement to flow onto the traveling lines of lacings, a distance equal to substantially double the length of a tip, after which the cement is shut ott' and this cement-treated portion is then ad vaneed to a point beneath the magazine t9 which carries a supply ot short lengths ot core wire 5() which wire is i'ed in :trom a roll lil by means ot the 'feed rolls which rolls are driven il'roin the main shalt ll through a belt- 53, pulley 5dr and gears whereby when a length ot this Wire is advanced to bring up against the wall 56 ot the hopper, it is severed by means ot the cutters and is ted bv gravity down through the hopper to be selected one at a time by the toothed AFeed-roll 58 through action ot the paul and ratchet mechanism, best illustrated in Figure 3. This mechanism operated by a pin 59 on the drum l() which engages the dog (30 pivoted at Gl on the bracket G2 so that each time this dog is engaged by the pin it pulls down the panl G3 through move nient of rod Get and arm (i5 thereby itetulirrt,r a short length of core ivire around through the guard tube Gti until the opening; t? is reached when the core wire is permitted to drop into the cement-treated portion ot the lacing B6.

The dies 2G are now caused to close by action ol' the lever 29 above described, thereby causing: the cutter (tl to .sever the lacing.: and the double length oll core, and tbe dies 2T to `told or wrap the ceinenttirated portion ol the lat-ingr about this core and lo hold the lut-ingr so l'olded duriinr the rotation of the drum on which the die block is mounted until the cement is dried or hardened which action is hastened by hat which applied through an electric heater (3th ree Figure S, mounted in the body ol the die bloeit.

No means are herein shown tor operating: the cutters 5T. but any suitable means may lie employed lor this rnu'rmee. Also the t'aces ol the toed rolls 52 may be corrugated, as shown in Figure l to act upon and roughen the surface ol the core wire as ted no as' to cause the fabric of the lacing to more closely adhere thereto when wrapped around and cemented to its surface.

In order` to maintain the lacingr in curved vlorin in cross section While being positioned in the space betvreen the dies 26, I have supported a grooved member 7l on the standard 72 and on the drum just in ilront the die block .i7 so that as the lacing is drawn into this space it is retained in this curved condition durinp; the time that the core section is deposited thereon, which curved condition ailso assists in the first operation ot the dies in wrappinior the fabric about the core.

After this short section ot tip core is deposited on the cement-treated section ot the lacing, the travel ot' the drum which is continuous novv causes the roll 30 on each lever 239 to engage its Iixed cam 3l which is supported above and in proximity to the drum thereby closing,- these tip-forming dies upon the lacing and as the cams are passed the dies remain during the travel ot the drum until the oppositely-disposed set of cams 73 which are lixedlv mounted on the bar 74: are engaged by the roll Sti which serves to move this lever 29 in the opposite direction thus separating the dies and permitting the severed end 'T5 ot the tip to tall upon the tra-veliner belt TG, uhich belt is driven :trom pulley T8 on the shal't lil through pulley 79 and pulley 8O to run the belt in the direction of the arrow and so deposit the lacings as released troni the dies into the receptacle 8l it beine understood that the forward end 75 ot the lacing' upon being' released by its block starts in the reverse direction towards the receptacle 8l. While the opposite end is still retained in its die block until that too is released by engagement with the earn T3 which permits both the second end ot the lacing' which has already started to travel back` to tali upon the belt and also releases the 'Forward en d ol'v the next length ot lacing to lall upon the tra velingg belt and start in its reverse direction towards the receptacle Sl.

Thus it will be seen that the operation is entirely automatic, the lacingbeing drawn inr from thereel 361 bythe traveler vthe die block' while its' dies are'- closed' upon the lacing to form a tip thereon,'thus advancing anotherl'engtl'i of lacifng'into position to be engaged by thedies i'n the next ysucceeding block and soV on, each set ofv dies forming a tip on the lacing as presented thereto.

` I do not wish to be restricted to the employment of a drumy onv which to mount my tip-forming devices as any means for advancing or moving these d-ie blocks may be employed; neither' do I wish to be restricted to the exact form of dies or means yfor formingthe tip" as -any suitable means may' be employed for this purpose.

I haveherei-n shown aipflurality of strands of lacing as being operated upon to be tipped, simultaneously, but I do not wish to be restricted to operating upon any particularnumber of lacings at the same time, as one vor any other desired number may be fed and simultaneously operated upon.
